This function maintains the main circuit DC voltage to the value set by [bA-32] instantaneous power fail-
ure non-stop level while decelerating if instantaneous power failure occurs or the main circuit DC volt-
age drops during operation.
The condition to activate this function is when all the conditions below are met.
• [bA-30] is 02 or 03
• In operation
• When the instantaneous power failure occurs at the control power supply or when the main circuit
DC voltage drops to [bA-31] instantaneous power failure non stop function starting voltage
If the instantaneous power failure time is short, continuous operation without interrupting output is pos-
sible. However, if undervoltage is observed upon instantaneous power failure, the output is interrupted
immediately and this function will be terminated. The operation after recovering from the instantaneous
power failure depends on the selection of how to restart after instantaneous power failure and under-
voltage.
When [bA-30] is 03, the normal operation can be restored if recovered from the instantaneous power
failure and the power is received before the output will be interrupted. However, it may decelerate and
stop depending on the [bA-31] setting. Details are given below.
This function is activated if the conditions to start operation mentioned above are met even if the power
line for J51 connector connected to R0 and T0 terminals are disconnected to be connected from P of
the main terminal to R0 and from N to T0, or even if the control power supply and main circuit power
supply are powered independently.
If the motor decelerates and stops as a result of this function activated, it will be forced to stop even if
[FW] is ON. Verify that the power is restored before powering on [FW] again when restarting.
